strftime - C Programing Filename is in chinese symbols -

i trying modify source code need create filename based on date filename being created chinese symbols. compiling using nmake visual studio , unicode.

i not sure whether code issue or compiler problem.

code extract:

   struct tm * timeinfo;     struct tm *__cdecl localtime(const time_t *t);     tchar buffer[80];     time_t rawtime;     rawtime = time(null);     time(&rawtime);     timeinfo = localtime(&rawtime);     strftime(buffer, sizeof(buffer), "%d%m%y%h%m%s", timeinfo);     prd->command[i] = '\0';      lptstr t;     (t = buffer; *t; t++) {         if ((*t != '<') && (*t != '>') && (*t != '\"') &&             (*t != '|') && (*t != '/') && (*t != '\\') &&             (*t != ':'))             prd->command[i++] = *t;     }     //lstrcat(prd->command, buffer);     = lstrlen(prd->command); 

well after investigation prompted possible duplicate, have working code. had expected , investigated tchar conversion, not come answer. did more investigation on , came across wcsftime. seems have worked , means not need make other modifications code work , compiles fine in vs2013.

working code:

        struct tm * timeinfo;     struct tm *__cdecl localtime(const time_t *t);     wchar_t buffer[80];     time_t rawtime;     time(&rawtime);     timeinfo = localtime(&rawtime);     wcsftime(buffer, sizeof(buffer), l"%y%m%d_%h%m%s", timeinfo);     prd->command[i] = '\0';     lstrcat(prd->command, buffer);     = lstrlen(prd->command);     s++;
